Abstract
Data derived from coronal eclipse spectra in the visible range are analyzed in terms of electron density and temperature in a coronal condensation using the method recently developed by Jefferies, Orrall and Zirker. A mean density and a certain amount of material are associated to each temperature. Abundances relative to Fe are derived for Ni, Cr, Mn, S, Ca. The absolute abundance of Fe is found to be 2 × 10−5. No absolute calibration is required. It appears that there must exist a non-negligible amount of ‘cold’ material (T e < 106K) in the corona, which cannot be observed in the visible spectral range.
